That's one way of looking at it. I'm not saying your wrong to think that way at all. But when you turn that thinking on it's head, you get a equally viable possibility:
Dak is playing out of his mind right now. And I don't see that changing anytime soon. I think that meeting last week probably in some way or another addressed that and acknowledged that the coaches need to get the hell out of the way and let Dak do Dak. If that means Zeke is in no way featured and doesn't get his snap count, so be it. Similar to 2016 they are going to ride the Dak train as far as it will take them.
And if they do, this season could turn special quick, fast and in a hurry.
